Sir Alex Ferguson urged Manchester United youngster Scott McTominay to represent Scotland at international level, even though England had expressed an interest in his services.
The 21-year-old has been impressive in the heart of midfield for Jose Mourinho's side this season, but will not be in contention for a World Cup place with England as he has already committed his future to Scotland.
His grandfather, Frank, has revealed that Ferguson was a key figure in McTominay's development at Manchester United and, alongside current manager Mourinho, pushed him towards rejecting the country of his birth for his ancestral home.
